CUB 3205

[terry beavers]

Hi! I'm a new member looking for an answer to a front pto problem. My cub 3205 s vacuum actuator will not disengage. I checked the switch seems to be working. Could it be a bad selinoid not letting the actuator release? Thanks,Terry

Hello & WELCOME to TBN!

I moved your thread to the Cub Cadet Lawn & Garden Forum.

I'm going to replace the vacuum selenoid.

Is it serviceable? It might have a piece of debris stuck in it preventing it from operating. I have to service water solenoids all the time at work. Even thought we have to filters in front of the solenoid. Just a thought.

Had this problem early on with my 8 yr old 3204. The electrical operated vac valve was serviceable (at least on the one that came on mine) & I took it appart and cleaned it well. Don't recall if I put any lube on the moving part(s) but it hasn't caused me any problems since then. If I did put any lube on some parts it would have most likely been the silicone spray I have and used for yrs that drys leaving only a film.

If you pull the line going from the solenoid to the actuator, does it disengage?

When I turn the pto switch off, the vacuum actuator releases some but not enough. When I disconnected the vacuum line it does release fully.When mowing the blades will decrease speed almost to a stop. I noticed it looks as if the actuator is not pulling shut all the way also.

I cleaned the solenoid with no luck. I didn't use any type of lube though. I will reclean and lube this time.

I had similar problem. My solenoid was getting plugged with dirt on the vent side port. You could try spraying WD-40 through the solenoid both when engaged and not engaged to try to clear passages. IF that doesn't work. I suggest replacing solenoid. Also, you might want to test the vacuum actuator with a mity vac tool or similar. Disconnect hoses to actuator, connect mity van and pump it down. SHould begin to pull at 3-4" Hg and be fully retracted by 10" Hg. Should stay retracted and hold vacuum without bleeding down.
